Can buttermilk be used to make butter cream frosting?

Here's why:

* Acidity: Buttermilk's acidity can react with the ingredients in buttercream, potentially affecting the texture and stability.

* Flavor: Buttermilk has a distinct tangy flavor that might not complement the sweetness of the frosting.

Instead of buttermilk, you can use:

* Milk: Regular milk is the most common ingredient in buttercream frosting.

* Heavy cream: For a richer and smoother frosting, you can use heavy cream.

* Sour cream: This option offers a slightly tangier flavor but can also affect the consistency.

If you're looking for a tangy twist on buttercream, try adding a small amount of lemon juice or vinegar to your regular recipe.
